COMBINED WRITING SHEET AND ENVELOP.

SPECIFICATON forming part of Letters Patent No. 738,891, dated September 15, 1903.

Application tiled October '7, 1902- Serial No. 126.324. (No model.)

To a/ZZ whom it may concern:

Be it known that I, EDMUND ECKART, a citi- Zen of the United States of America, and a resident of New Rochelle,Westchestercounty, State of New York, have invented certain new and useful Improvements in a Combined Writing-Sheet and Envelop, of which the following is a specification.

The invention relates to an improved blank designed to serve as a writing-sheet and also as an envelop to inclose saine, that part of the blank serving as the face of the envelop being perforated or formed with an opening to render visible the sendees address heading the communication on the writing-sheet, whereby a separate envelop or separately addressing the envelop is avoided, and other important advantages result, as hereinafter pointed out.

The preferred form of the blank is illustrated in the accompanying drawings, in which Figure l is a plan view of the blank. Fig. 2 is a similar view showing first fold. Fig. 3 is a view of the completed article viewed from the rear. Fig. 4 is a face view of the article, and Fig. 5 is a transverse section through the envelop just prior to the aps being sealed.

In the preferred form illustrated the blank l is substantially rectangular in shape and for convenience in description is showudivided into four parts, 2, 3, 4, and 5, by the vertical and horizontal median lines 6 6 and 7 7, respectively. I prefer to crease or score the blank along the median lines 6 6 and 7 7 to indicate the lines of fold to the user. The free edges of section 3 are provided with integral suitably-gummed flaps 8 and 9, and as the opposite side of this section serves as the face of the envelop I form in the same a perforation or opening 10 of -any suitable size and shape.

Section 2 of the blankis designed to receive, in the position indicated by dotted lines 11, the name and address of the sendee naturally heading the communication, the remainder of this section and sections 4 and 5, as well as the back of sections 2 and 4:, serving to receive the body of the communication or other desirable matter.

Assuming the blank of the form described, with the sendees name and address heading the communication as directed, the blank is folded along the median line 6 G, assuming the form shown in Fig. 2. The blank is next folded on the median line '7 7, the bottom edge being brought into practical alinement with the edge next flap 8 and the tlaps 8 and 9 secured in place-that is, to the back of section -ewhen the article is complete, assuming the form shown in Fig. 3. It will be seen that the sendees name and address (indicated by dotted lines 1l) appearing through opening 10 in section 3, as shown in Fig. Lt, serve as a direction for the transmission of the envelop and contents without the necessity of a separate envelop 0r of separately addressing the envelop, the remainder of the communication remaining as invisible and secret as though inclosed in the ordinary envelop.

In the use of my invention Several important advantages are gained over any similar article now in use. For instance, a single sheet serves both as awriting-sheet and as an envelop therefor, and in sending out mailmatter several steps heretofore necessary are dispensed with. The weight and expense of an additional envelop is saved, error in sending letters or other inclosures in wrong envelops is prevented, no separate addressing of an envelop being required, and an exact record of the matter on the Writing-sheet and also of the official stamp as to time of mailing and receipt on a single and inseparable sheet.

It may be found advisable to secure a transparent sheet of material over the opening lO, in which event the transparent sheet is cut of a shape corresponding to and slightly larger than opening l0 and fixed in place prior to folding the blank, when the sendees name and address will be Visible through such transparent sheet and be protected from erasure or change. I do not deem such arrangement essential to form a perfect article, but consider such addition within the scope of my invention.

I contemplate, of course, so forming the blanks as to give the resultant article, note, or letter commercial size and shape, and, if desired, in commercial or other uses section 2 of the blank may be printed with usual letter-head with indicated space for sendees name and address, and it may be found desirable to make opening 10 of such size as to expose sufficient of the printed head of section 2 to indicate the senders name and address for return in event of non-delivery.

In ordinary use of the invention it will probably be found expeditious to fold the blank on the median line 6 6 and write the sendees name and address on that part of section 2 disclosed through opening 10, then opening the blank and writing the desired communication with such naine and address as the usual heading.

I am aware that it is not broadly new to form an envelop and Writing-sheet of a single blank and that it is also old to perforate an envelop to permit the sendees name and address written on a separate writing-sheet to appear; but I do not believe an article having the characteristics and advantages of my invention has been before devised.

What I claim as new is- 1. As a new article of manufacture, a combined writing-sheet and envelop formed of a single blank, integral flaps formed on adjacent edges of the blank, and coeXtensive with half the length of such edges, and an opening in that part of the blank adjacent the flaps.

2. As a new article of manufacture, a coinbined writing-sheet and envelop formed of a single blank with integral flaps coextensivewith a part of adjacent edges, the blank being formed with an opening adjacent said flaps, said blank being designed to be folded along its vertical median line, then folded along its horizontal median line, and finally completed by securing the flaps in place.

3. As a new article of manufacture, a combined writing-sheet and envelop formed of a single blank provided with integral flaps on contiguous edges and provided with an opening adjacent said flaps, said blank being scored vertically from top to bottom and on a horizontal line from edge to edge, said blank being folded on the vertical score and then the folded portions being again folded on the horizontal line, the [laps securing the folds to complete the envelop.

Signed by me at New York city, New York, this 2d day of October, 1902.
